The full interview is on YouTube. RR has committed to spending only the amount received in tax receipts. Money coming in must equal money going out. How do we feel about that?
The UK is not a household. The State issues our money, either directly by state spending into the economy or by quantitative easing, whereby the Bank of England created the money to buy up bonds with the objective of releasing more money into the economy.
The state does not have to 'earn' money before it can spend it, it can put its 'created' money into the economy, where it will circulate and drive economic activity. Taxation drains excess money from the economy. Without taxation there would be too much money around, which would cause inflation, even hyperinflation in some circumstances.
There will always be less money 'coming in' than there is money going out because people tend to save spare money if they don't need or want to spend it all. 'Balancing the books' in accountancy terms just means accounting for all the money flowing in and out. It shows if there is a surplus or a deficit. Deficits matter to everybody except a state, because no-one except the state can create money, if they did it would be called counterfeiting and would be illegal. But states have to create money because if they didn't there wouldn't be enough money in circulation to accommodate a growing population.
There is far more money in circulation now than there was 50 years ago; if there wasn't everyone would have a smaller and smaller share of the finite amount of money available. Just imagine if only the money available for the post war UK population of 45 million had to be 'shared' among out current population of 66+ million. The extra money needed has been mainly put into the economy by the state.
The only way a state can run a surplus without impoverishing its population would be for it to take in more money from foreign trade than it pays out in state spending. As this is far from the case for most countries the state has to run a deficit because of the fact that people save, spend money on imports or just on foreign holidays... Running a deficit is not bad unless it leads to excessive inflation ( a modest rate of inflation isn't harmful, as we know from years of inflation in low single figures).
This a basic, simplistic explanation of a very complex topic.
The real issue is how money is distributed within the population; in our current economic situation money tends to flow upwards, hugely enriching certain parts of the population and impoverishing others. If one thinks that that is not a bad thing, fair enough, but if one believes that distribution should be more equable, that there shouldn't be large numbers of people living in poverty in a supposedly 'wealthy' country it is a situation to be deplored...
